Unable to use ResetPasswordAsync: 'No IUserTwoFactorTokenProvider<TUser> named "Default" is registered.' even after configuring Identity #9386

DuHK created 16 days ago

Hi ABP Support Team,

I am using ABP Blazor Web App version 9.1.0 with PostgreSQL and EF Core. I want to implement the "force password change on next login" flow using ResetPasswordAsync and GeneratePasswordResetTokenAsync from IdentityUserManager. However, I always get the following error when calling these methods:

System.NotSupportedException: 'No IUserTwoFactorTokenProvider<TUser> named 'Default' is registered.'

My configuration in CoreBackendHttpApiHostModule.cs:

context.Services.AddIdentity<IdentityUser, IdentityRole>() .AddEntityFrameworkStores<CoreBackendDbContext>() .AddDefaultTokenProviders();

I have installed Microsoft.AspNetCore.Identity.EntityFrameworkCore. My CoreBackendDbContext inherits from AbpDbContext<CoreBackendDbContext>. I do not have any custom User or Role classes, I am using the default IdentityUser and IdentityRole. I have cleaned and rebuilt the solution, but the error persists. The code that causes the error:

var result = await _userManager.ResetPasswordAsync(user, input.ChangePasswordToken, input.NewPassword);

What I have tried: Adding correct using statements. Ensuring only one call to AddIdentity<> exists. Registering DataProtectorTokenProvider<IdentityUser> manually – still doesn't work. Could you please advise what might be missing in my configuration, or if there is any ABP-specific requirement to enable the default token provider for password reset?

Thank you very much!

context.Services.AddIdentity<IdentityUser, IdentityRole>() .AddEntityFrameworkStores<CoreBackendDbContext>() .AddDefaultTokenProviders();

Hi, you don't need to add this configuration, if your project depends on the Volo.Abp.Identity.Pro.Domain project, then there is a similar configuration is already made on the module side. So, you can remove this configuration. Probably, it's causing this problem because it overrides the default registration:

context.Services.AddIdentityCore<IdentityUser>().AddTokenProvider(TokenOptions.DefaultAuthenticatorProvider, typeof(AbpAuthenticatorTokenProvider));

Therefore, can you please remove the related configuration in your side, and check if it fixes the problem or not?

I deleted the above configuration but when I run it again, I still get this error. Give me an example so that when a user changes their password the first time they log in, the token is returned.

here is the function to get the reset password token

Your module need to depend on AbpIdentityAspNetCoreModule or you should add the following configuration:

public override void PreConfigureServices(ServiceConfigurationContext context)
{
    PreConfigure<IdentityBuilder>(builder =>
    {
        builder.AddDefaultTokenProviders()
    });
}
